Baxi Combustion Front Plate Insulation 17 Section S136774

The Baxi S136774 is a combustion front plate insulation panel, manufactured by Baxi for use in Potterton gas appliances. It sits at the front face of the combustion chamber, where it shields surrounding panels and components from radiant heat and helps hold working temperature steady around the burner area. Over time the insulating material degrades, so the panel is treated as a serviceable item during burner and heat exchanger work.

• The insulation panel is crumbling, flaking or shedding fibres when touched
• Visible scorching, charring or heavy discolouration across the front face
• The panel has cracked, warped or broken away from its mounting points
• Heat damage or sooting on adjacent panels and components behind the front plate
• The panel is missing or has been removed during earlier repair work

• Confirm the appliance model and, where available, the GC number against the compatibility list
• Check the existing panel against part number S136774 and alternative number 1134554 before fitting
• Inspect the surrounding seals and gaskets while the combustion chamber is open, as these are commonly disturbed during the same repair
• This part is fitted to a gas appliance; installation must be carried out by a Gas Safe registered engineer.
